Dis-Integrated 6502 Running Programs; Acting Like Computer
[Eric Schlaepfer] tends to turn up to Maker Faire with projects you simply don’t want to miss. This year is no different. Twelve months ago we delighted in seeing his 6502 processor built from an enormous reel of discrete MOSFETs. At the time it was freshly built and running random code to happily blink the LEDs reflecting activity in the registers. This year he’s given that blinking meaning and is running real programs on his Monster 6502 processor. …read more
Arduino Cinque – The RISC-V, ESP32, WiFi, Bluetooth Arduino
This weekend at the Bay Area Maker Faire, Arduino in conjunction with SiFive, a fabless provider of the Open Source RISC-V micros, introduced the Arduino Cinque. This is a board running one of the fastest microcontrollers available, and as an added bonus, this board includes Espressif’s ESP32, another wonderchip that features WiFi and Bluetooth alongside a very, very powerful SoC.
Details on the Arduino Cinque are slim at the moment, but from what we’ve seen so far, the Cinque is an impressively powerful board featuring the RISC-V FE310 SoC from SiFive, an ESP32, and an STM32F103. The STM32 appears to …read more
FAA’s Drone Registration System Struck Down For Hobbyists
The US Court of Appeals for the D.C. Circuit has struck down a rule requiring recreational drone users and model aircraft pilots to register their drones with the FAA.
This began when [John Taylor], an RC hobbyist and attorney, filed suit against the FAA questioning the legitimacy of the FAA’s drone registration program. This drone registration began early last year, with the FAA requiring nearly all drones and model aircraft to be registered in a new online system. This registration system caused much consternation; the FAA Modernization And Reform Act of 2012 states, ““…Federal Aviation Administration may not promulgate any …read more
KiCAD Best Practices: Library Management
One common complaint we hear from most new KiCAD users relates to schematic and footprint libraries. The trick is to use just one schematic symbol and footprint library each with your project. This way any changes to the default schematic libraries will not affect your project and it will be easy to share your project with others without breaking it. I’ve spent some time refining this technique and I’ll walk you through the process in this article.
We have covered KiCAD (as well as other) Electronic Design Automation (EDA) tools several times in the past. [Brian Benchoff] did a whole …read more
Monoprice Releases Their Mini Delta Printer (On Indiegogo)
Around this time last year, Monoprice quietly unveiled a small, $200 3D printer. At the time, a fully functioning printer at this price point wasn’t unheard of. A good 3D printer at this price point was. It turned out this printer was actually fantastic and completely changed the value proposition of desktop 3D printers.
In the year since the release of the MP Select Mini printer, Monoprice has been hard at work bringing costs down, reworking designs, and creating an even less expensive printer. Now, it’s out. It’s available for pre-order on Indiegogo right now. Is this still a $150 …read more
